1. Yes, agree it's an ethical question. Very difficult to make a company move based on ethical arguments.
2. Boycott. Why not? Sure it's unlikely to change anything. But we're potentially boycoting on moral grounds because it's the "right" thing to do. My personal story is that I have not bought anything from Samsung in over 8 years becasue they majorly screwed me over on one of my work projects. I'm sure Samsung is feeling THAT impact to their bottom line. No? I still feel good about it anyways and will keep my personal boycott in place.
3. Release the 978 prints? Probably not if they aren't released already.
